Lens Mounts
A lens mount is an interface – mechanical and often also electrical – between a photographic camera body and a lens. It is a feature of camera systems where the body allows interchangeable lenses, most usually the rangefinder camera, single lens reflex type, single lens mirrorless type or any movie camera of 16 mm or higher gauge. Lens mounts are also used to connect optical components in instrumentation that may not involve a camera, such as the modular components used in optical laboratory prototyping which join via C-mount or T-mount elements. Mount types A lens mount may be a screw-threaded type, a bayonet-type, or a breech-lock (friction lock) type. Modern still camera lens mounts are of the bayonet type, because the bayonet mechanism precisely aligns mechanical and electrical features between lens and body. Screw-threaded mounts are fragile and do not align the lens in a reliable rotational position, yet types such as the C-mount interface are still widely in use ...

Bajonett Manual Minolta
Autogas or LPG is liquefied petroleum gas (LPG) used as a fuel in internal combustion engines in vehicles as well as in stationary applications such as generators. It is a mixture of propane and butane. Autogas is widely used as a "green" fuel, as its use reduces exhaust emissions by around 15% compared to petrol. One litre of petrol produces 2.3 kg of when burnt, whereas the equivalent amount of autogas (1.33 litres due to the lower density of autogas) produces only 2 kg of when burnt. CO emissions are 30% lower, compared to petrol and by 50%. It has an octane rating (MON/RON) that is between 90 and 110 and an energy content (higher heating value—HHV) that is between 25.5 megajoules per litre (for pure propane) and 28.7 megajoules per litre (for pure butane) depending upon the actual fuel composition. Autogas is the third most popular automotive fuel in the world, with approximately 16 million of 600 million passenger cars powered using the fue ...

Arri
The Arri Group () is a German manufacturer of motion picture film equipment. Based in Munich, the company was founded in 1917. It produces professional motion picture cameras, lenses, lighting and post-production equipment. Hermann Simon mentioned this company in his book ''Hidden Champions of the 21st Century'' as an example of a " hidden champion". The Arri Alexa camera system was used to film Academy Award winners for Best Cinematography including ''Hugo'', ''Life of Pi'', ''Gravity'', '' Birdman'', '' The Revenant'' and '' 1917''. History Early history Arri was founded in Munich, Germany on 12 September 1917 by August Arnold and Robert Richter as Arnold & Richter Cine Technik. The acronym ''Arri'' was derived from the initial two letters of the founders' surnames, ''Ar''nold and ''Ri''chter. In 1924, Arnold and Richter developed their first film camera, the small and portable Kinarri 35. In 1937, Arri introduced the world's first reflex mirror shutter in the Arriflex 35 c ...

Canon FD Lens Mount
The Canon FD lens mount is a physical standard for connecting a photographic lens to a 35mm single-lens reflex camera body. The standard was developed by Canon of Japan and was introduced in March 1971 with the Canon F-1 camera. It served as the Canon SLR interchangeable lens mounting system until the 1987 introduction of the Canon EOS series cameras, which use the newer EF lens mount. The FD mount lingered through the release of the 1990 Canon T60, the last camera introduced in the FD system, and the end of the Canon New F-1 product cycle in 1992. The FD mount was based upon and replaced Canon's earlier FL mount (which in turn had replaced the R mount); FD-mount cameras can use FL lenses in stop-down metering mode. Though never officially explained by Canon, others have attempted to assign a meaning to the "FD" designation. One such attempt states that the "FD" notation stands for "Focal-plane shutter with Dual linkage for diaphragm control"; in actuality, there were two li ...

135 Film
135 film, more popularly referred to as 35 mm film or 35 mm, is a format of photographic film used for still photography. It is a film with a film gauge of loaded into a standardized type of magazine – also referred to as a cassette or cartridge – for use in 135 film cameras. The engineering standard for this film is controlled by ISO 1007 titled '135-size film and magazine'. The term 135 was introduced by Kodak in 1934 as a designation for 35 mm film specifically for still photography, perforated with Kodak Standard perforations. It quickly grew in popularity, surpassing 120 film by the late 1960s to become the most popular photographic film size. Despite competition from formats such as 828, 126, 110, and APS, it remains the most popular film size today. The size of the 135 film frame with its aspect ratio of 1:1.50 has been adopted by many high-end digital single-lens reflex and digital mirrorless cameras, commonly referred to as " full frame".

Canon FL
Canon FL refers to a lens mount standard for 35mm single-lens reflex cameras from Canon. It was introduced in April 1964 with the Canon FX camera, replacing the previous Canon R lens mount. The FL mount was in turn replaced in 1971 by the Canon FD lens mount. FL lenses can also be used on FD-mount cameras. Many mirrorless interchangeable-lens cameras are able to use Canon FL lenses via an adapter. FL cameras * Canon FX (1964) * Canon FP (1964) * Canon Pellix (1965) * Canon FT QL (1966) * Canon Pellix QL (1966) * Canon TL (1968) FL lenses Zoom Wide-angle (under 50mm) Standard (50–60mm) Source: Canon released 3 'levels' of standard lenses (exc. macro).

Image Sensor Format
In digital photography, the image sensor format is the shape and size of the image sensor. The image sensor format of a digital camera determines the angle of view of a particular lens when used with a particular sensor. Because the image sensors in many digital cameras are smaller than the 24 mm × 36 mm image area of full-frame 35 mm cameras, a lens of a given focal length gives a narrower field of view in such cameras. Sensor size is often expressed as optical format in inches. Other measures are also used; see table of sensor formats and sizes below. Lenses produced for 35 mm film cameras may mount well on the digital bodies, but the larger image circle of the 35 mm system lens allows unwanted light into the camera body, and the smaller size of the image sensor compared to 35 mm film format results in cropping of the image. This latter effect is known as field-of-view crop. The format size ratio (relative to the 35 mm film format) is k ...

Flange Focal Distance
For an interchangeable lens camera, the flange focal distance (FFD) (also known as the flange-to-film distance, flange focal depth, flange back distance (FBD), flange focal length (FFL), back focus or register, depending on the usage and source) of a lens mount system is the distance from the mounting flange (the interlocking metal rings on the camera and the rear of the lens) to the film or image sensor plane. This value is different for different camera systems. The range of this distance, which will render an image clearly in focus within all focal lengths, is usually measured to a precision of hundredths of millimetres, and is not to be confused with depth of field. Lenses can be adapted from one mount (and respective FFD) to another. FFD determines whether infinity focus can be accomplished with a simple non-optical adapter. Optics to correct for distance introduce more cost and can lower image quality, so non-optical lens adapters are preferred. A simple non-optical ada ...

Cine Lens
Cine lenses or cinema lenses are lenses that are designed especially for cinematography, and whose main distinguishing feature from conventional photographic lenses is the "clickless" or "declicked" aperture ring. Markings on the aperture ring indicate T-stops rather than f-stops as used in still photography. Furthermore, it is a desirable characteristic for cine lenses to occupy the same form factor as each other so as to be readily interchangeable and identical in operation. This particularly applies to lenses with different focal lengths. In order to maximise interchangeability, lenses within a series of cine lenses are often identical in transmittance of light (maximum T-stop). Anamorphic lenses for cinematography may also be classified as cine lenses. Manufacturers The following companies produce cine lenses: *Angénieux *Arri *Atlas Lens Co. *Canon Inc. *Cooke Optics *Fujifilm *Irix * Leica *Rokinon *Samyang Optics *Sigma Corp. * Vantage® * ZeissNitecore*Venus Optics ...
